WIND-ASSISTED PARACHUTE PROPULSION SYSTEM

摘要

A wind-assisted parachute propulsion system for boats, watercrafts and yachts using a parachute with a canopy substantially shaped as an equilateral triangle with a semi-ellipses attached to each side of said triangle according to Fig. 4. The canopy is attached with a limited number of three bridle lines (6) converging at a tether (4). The tether is led through a swivel (5) rotatably attached to the upper section of a mast pole and wound over the drum of a winch (3) attached inside the bottom section of the mast pole. The self-supporting mast pole (1) is attached to the vessel deck (10) at the bottom with a base plate (2) or in variant no. 2 (Fig. 3), the mast pole is preferably a telescopic mast extending upwards over the deck. By winding the tether, the winch retracts the parachute inside the mast pole (Fig. 2), reducing its surface area or fully retracting it. The parachute is launched from the mast pole by loosening the tether using compressed air generated by the winch blower or by pulling the emergency line (9) attached to the parachute canopy.
